ABSTRACT
Near-infrared to visible upconverted fluorescence was observed in the Al[sub 2]O[sub 3]–SiO[sub 2] glass containing Eu[sup 3+] ions during femtosecond laser irradiation. The dependence of the intensity of the Eu[sup 3+] emission on the pump power reveals that the three-photon excitation is dominant in the upconversion process from near-infrared into the visible fluorescence. The analysis of the upconversion mechanism indicates that upconversion fluorescence comes from the three-photon simultaneous absorption that leads to the population of the 4f levels via the excitation of the charge transfer state of the Eu[sup 3+] ions. © 2004 American Institute of Physics.
